I checked out the latest version and runs perfect with adding QLineEdit
and QPushButton controls to the grid. Great!  :-)

In my code I have public arrays for all those controls. In tutorial 6, I
think the LCDRange() has no public class member variable assigned. (Same
in C++ original tutorial.) I don't know if this difference causes
changing the line in t6/main.php:

$this->grid->addWidget(new QPushButton("a",$this), $row, $column, 0);
or
$this->grid->addWidget(new QLineEdit("a",$this), $row, $column, 0);

to segfault. (Garbage collector kills the referenced QLineEdit?)

(I have the same controls in my program and they work well. Anyway, I
don't think anyone would create a control without some way to access it
(i.e. a class member object). Then I just wonder why the original T6
works.  :-)  )
